ROLLING-MILL FO R ROLLING WIRE AND RODS.

SPECIFICATION forming part of Letters Patent No. 252,467, dated January 1'7, 1882. Application filed March 17, 1881. (No model.) Patentedin England January 27, 1881.

To all whom it may concern:

Be it known that I ALFRED HUGHES, of Glasgow, in the county of Lanark, North Britain, wire-roller, have invented Improvements in Rolling Metal Wires, Rods, and the Like, andin Machinerytobe Employed Therein, (for which I have applied for Letters Patentof the UnitedKingdom of Great Britain and Ireland,

No. 358, by petition, to bear date the 27th day of January, 1881,) of which the following is a specification. a My said invention relates to improvements in rolling metal wires, rods, and the like, and in "machinery to be employed therein, and has for its object toso arrange and combine the rolls and other parts together that acompound machine is produced, wherein the rolling can be effected continuously from the bloom to the finished article, and a great saving of manual labor is'efi'ected, the process conducted more rapidly than hitherto, and reheating between the various operations dispensed with.

Figure 1 of the accompanying drawings represents, in plan, machinery or apparatus arranged and combined according to my invention.

A motive-power engine, A, of any suitable or convenient construction, is provided, its cylinders ahaving pistons with double pistourods 12 0 projecting from both covers of the cylinders, the said rods giving rotary motion totwo shafts, B and 0, respectively, at either end or side of the machine. 0 are the eccentries for actuating the slide-valves of the cylinders. The shalt B carries a fly-wheel, b and through gearing d drives the rolls D of the breaking-down train, which are the rolls by which the bloom is first acted upon after leaving the furnace. These rolls are shown in front elevation separately and drawn to a larger scale in .Fig. 2. The other shaft, 0, through gearing drives a series of rolls arranged opposite the first-mentioned rolls D, and placed in double pair's, side by side, in the relative position shown in plan in Fig. l, and in side elevation, drawn to alarger scale, in

Fig. 3, and numbered 1, 2, 3, and 4, the finish-V ing-rolls being marked 5. Fig. 4 is a-transverse section, taken between sets of th ese rolls,

and Fign5 is a transverse section taken through a set of the same, both figures being drawn to a larger scale, and taken from the point of view indicated by the arrow in Fig. 1. The said series of rolls constitute the wire-mill or rolls by which the billet or rod, after it leaves 5 the rolls D, is continuously acted upon to produceihe wire or finished article, the reducing-grooves in the said series of rolls gradually lessening from the firstgr-oove in the first set ofrolls, 1, to the finishing-rolls 5, being pref- 6 erably such as to give alternately square and oval forms to the rod or bar acted upon until the last pair of rolls is reached, which will, of course, have grooves of the requisite shape for finishing the wire, rod, or other article. The 6 bar being rolled, after it has passed through one pair of each double pair of rolls is automatically fed back through the other pair of each double pair of rolls by guiding appliances provided at each groove in each double pair 7 of rolls. In Fig. 5 this guiding appliance is illustrated in vertical section. It consists at bottom of a fixed bed or table, f, level with the groove at the upper surface of the lower roll, as, of the first pair of rolls and with the 7 groove at the uppersurface of the upper roll, y, of the other pair of rolls, the said tablef extending from roll to roll, as shown. Above this table f is a hinged or pivoted guide-piece, g, centered at g (to any suitable projection 8 from a convenient part of the framing,) and forming a lever of the first order, the one end at 9 bearing against the upper roll, to, of the one pair of rolls, about level with the groove at the under part thereof, by the weight of the 8 other end at g, which is curved over and partly around the upper roll, y, of the second pair of rolls, from which it is kept from rising too far by a screw, it, capable of adjustment.

The table f and upper part, g, are shown in 9 transverse section in Fig. 6 and in side elevation in Fig. 7, wherebyit will be seen that the two parts together form between them a passage of the requisite shape to receive the rod as it issues from the groove of the rolls,'which 9 shape is or may be a shape corresponding to the groove ofthe roll in conjunction with which the guiding appliance is used. At the opening of the guide-piece g at g is. another curved guide-piece, 1 level with the groove at the top I rod or bar being directed in its course from above by a counterweighted lever, 76, centered at 70 whose one end, k bears against the under side of the roll y, aboutlevel with the groove therein. This table j and lever 70 maytogether form a guide of the shape of the rod as it leaves the grooves of the rolls 3 z.

xAs before stated, the guiding appliances may be affixed to or carried by any convenient part of the framing. In the arrangement of the upper guide shown in the drawings a slotted bar or carrier, 4, extends from housing to housing, and is adjustable vertically in slots in the said housing and fixed in position by nuts, as shown in Fig. 6, or by set-screwsor wedges, or other.- wise. A box consisting of two side plates, 8, connected by the transverse piece 8 having a pin, 8 formed thereon, is carried by the bar r, the pin s being passed through the slotin the said bar and fixed by a nut, s, in the horizontal position to which the box has been adjusted on the bar r. The tablef is supported in this box, resting upon the bottom 8 thereof, a projectiomf keeping the said table f in place. The pin 9 which forms the center for the lever g, is carried by the sides 8 of the box, as shown in Figs. 6 and 7.

The guides i and j are shown as being carried by rods t and 3' adjustable vertically in slots in the housings, as described with regard to the upper guide, the transverse adjustment being obtained by the bolts t and 7' being shifted to one side or the other and fixed in position by the nuts 6 andj.

The pin W, on which the lever 70 turns, may be carried by the checks or side plates of the guide or table j, or it may he a bar extending from housing to housing and adjustable and fixable in slots therein, as before described with regard to the other guides, and the box for the screw it may be carried in a similar manner; but it is to be understood that I do not limit myself to the precise arrangements hereinbefore described for carrying and adjusting these guiding appliances. v

The rolls of the various sets are preferably arranged as shown in Figs. 1 and 3, so that each pair of the double pairs of rolls 1 2 3 at are all in double line and upon two axes, one for all the corresponding rolls of each pair. At the end of the series and upon an axis common to one row of the other rolls is the pair of rolls 5, for giving the final form to the wire, rod, or the like.

The rolls of the wire-mill are driven by a driving-wheel, on the shaft (J, gearing with a pinion, l, on the shaft L, which forms an axis common to all the lower rolls of the one-pair of rolls of each double pair, the upper rolls being driven by gearing-pinions at m. The rotation of the rolls of the other pair of each double pair of rolls is obtained from the pinion 1 (see also Fig. 4) upon the shaft L, gearing into the pinion a on the shaft N, which forms an axis common to all the lower rolls of the pairs of rolls driven thereby, the upper rolls of such pairs being driven by pinions, as at 1), corresponding to those at m.

The pinions and driving-wheels are preferably formed with two concentric rings of teeth, the teeth of which rings break bond with each other.

Fig. 8 represents one of the pinions on or 10. Its ends are preferablyof the clutch-like shape shown also in end view in this figure, engaging in'similarly-formed boxes in the shaft, to which they are thereby attached, so as to give rotation thereto.

.In rolling metal wires, rods, bars, or the like the bloom from the furnace is passed'through the rolls D at the one side of the machine a number of times necessary to reduce it to a convenient size for treatment in the wire mills or-rolls at the opposite side of the machine, and issues from the said rolls D in the form of a billet, which, after its ends have been sheared off, is passed through the first grooves in the first or upper pair of rolls ot'the double pair 1 of the series at the opposite side of the machine, then back through the next grooves,

andvis then automatically passed by a'curved" guide, like that hereinbefore described, be-

tween the next grooves, which are on the other or lower pair of rolls of this double pair. Then between the next grooves, whichare on the first-mentioned pair of rolls, and theneeby a curved guide, like that hereinbefore referred to, between the other grooves which are on the second pair of rolls. The rod or bar or the like is then passed in through the next two grooves, which arein the next double pair of rolls 2, and thence through the remaining grooves, of which there may be fivevizfl, two each in two double pairs of rolls (3 and 4 in the drawings) and the last in the pair of finishing-rolls 5.

Curved guides, such as are hereinhefore described, will be arranged in each double pair of rolls, similarly to the arrangement shown in Fig. 5, to guide the rod, bar, or wire, or the iike from the one pair of rolls to the other pair of rolls of each double pair of rolls, the said pairs of rolls being arranged in the relative po-v sitions shown in Fig. 5, so that thesaid rod, bar, or wire, or the like will be delivered antomatically from the one pair to the other of each double pair of rolls of the series, and so back to that side of the series of rolls at which it was fed in, and a man standing on this side tion or arrangement, and is provided with the usual or necessary adjuncts of engines, and the gearing by which the motion of the said engine is transmitted to the rolls may be arrolls in any other desired direction.

tially as before described, but so as to pass the rod,bar, or wire, or the like through the For example,in order to deliver the rod, or bar, or wire, or. the like from the last rolls (at at the same side at which the deliveries from the other rolls were made, a curved guide simi lar to those hereinbefore described may be carried round beneath the lower roll of the last pair of rolls, so as to pass the said rod or i bar back under the pair of rolls through which it last passed, (before passing it to the last pair of finishing-rolls 5,) and deliver the said rod or bar at the back of the rolls for enabling it to be conveniently passed through the finishing-rolls for delivery at the front side of the rolls. In Fig. l the course of the rod, bar, or wire, or the like through the rolls of the wire-mill is indicated by dot-and-pick lines. For the sake'of clearness the guiding appliances are omitted from Figs-1 and 3.

I claimi 1. The combination of rolls for rolling wire and the like in double pairs, one pair behind and at a less altitude than the other pair, and suitable guides for guiding the material from the pass in the front or upper pair to and so as to return it through the pass in the rear or lowermost pair, substantially as described.

2. In combination with the rolls arranged as described, a fixed bed or table, f, and pivoted guide-piece g, the bed-or table extending from the upper surface of the lower roll of the first and upperpair of rolls to the upper surface of the upper roll of the second or lower pairof rolls, the end bearing against the upper roll of the first pair of rolls and the other end, 9 curved over and partly around the upper surface of the upper roll of the second pair of rolls, substantially as and for the purpose set forth.

3. In combination with the rolls arranged as described, a curved guide-piece, 6, table j, and counterweighted pivoted lever 70, the guide piece being level with the upper surface of the lower roll of the second and lower pair of rolls, the table extending from the upper side of said lower roll to the front of the machine, and the lever 7;, having one end, k bearing against the under side of the upper roll of the second pair of rolls and the other end extending toward the front of the machine substantially parallel with the table, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALFRED HUGHES.
